New features

• Generator: Added GeneratorOptions.Parallel
  • The option allows to disable parallel processing when generating assemblies. This is useful in some cases where parallel processing may be unstable.
• CLI: Added --no-parallel flag
  • The option allows to disable parallel processing when generating assemblies

Fixes

• Runtime: Improved class injection for metadta v29
  • Added more Class::Init substituted
  • Resolve GetTypeInfoFromTypeDefinitionIndex properly
• Generator: Fixed generating methods that contain ValueType parameters
• Generator: Fixed generating methods with Il2Cpp*Array<T> parameters
• Generator: Fixed size of bool fields in Il2Cpp structs (booleans in Il2Cpp are 1 byte)
• Generator: Fixed a NullReferenceException for some classes that have indexers

Version 1.0.0

Changelog

Major changes

• Removed netstandard2.0 target framework
• Added net6.0 target framework for the runtime and CLI
  • CLI and generator API support net4.6 to allow use of the tools with Visual Studio extensions
• Refactored code structure:
  • Il2CppInterop.Generator - API for analyzing Il2Cpp code and generating proxy assemblies. This is comparable to the old LibAssemblyUnhollower
  • Il2CppInterop.Runtime - API for interacting with Il2Cpp at runtime. This is comparable to UnhollowerBaseLib and UnhollowerRuntimeLib
• Overhauled wrappers for Il2Cpp runtime methods and structs
  • The wrappers can now be generated automatically from libil2cpp source code, which should enable faster fixes and updates when Il2Cpp version updates
• Removed all obsolete types and methods
• Removed support for Il2CppDumper. Il2CppInterop now provides primary support only for Cpp2Il

New features

• Added module that enables support for patching Il2Cpp methods with HarmonyX
• New API for programmatically generating proxy API: Il2CppInteropGenerator
• New API for initializing Il2CppInterop runtime: Il2CppInteropRuntime

Acknowledgements

This major overhaul wouldn't be possible without major contributions from @Kasuromi and @js6pak!
